Title: Improvements relating to the production of fibrous sheet materials
IPC: D21H13/34
Filed: 1961-09-12
Abstract: A fibrous sheet material consists wholly or partly of fibrils regenerated from eucollagen.  Eucollagen is a form of collagen, soluble in acidic media, obtained by treating raw material (skin, bone, ossein, sinew or the like) with alkali, in the presence of a salt, e.g. sodium sulphate, which protects the collagen from hydrolysis.  Material obtained in this way can be dissolved in acidic buffer solutions and regenerated therefrom in fibrous form by a change of pH or ionic concentration or the addition of mucopolysaccharides, tannin, or large molecules.  The fibrils may be produced by regeneration in an aqueous slurry of fibres, which may be of tanned or untanned leather or of vegetable origin.  The fibres are then formed into a sheet by filtering and drying.  The materials so formed may be plasticized or tanned.

Title: Improvements in or relating to fluid pressure regulating devices
IPC: G05D16/10
Filed: 1958-10-14
Abstract: 864,585. Fluid-pressure servomotor control systems. BOSCH G.m.b.H., R. Oct. 14, 1958 [Oct. 19, 1957], No. 32675/58. Class 135.  A pressure-regulating device for an hydraulic system including a reservoir 3, connected to a pump 1 supplying through a check valve 4 pressure liquid to a storage vessel 7 and consuming apparatus M, e.g. an hydraulic motor, comprises a valve piston 32 displaceably mounted in a cylinder 25 against the resistance of a spring 34 to interconnect lines 35, 37 connected to the pump and reservoir respectively to unload the pump on the opening by system pressure of both low and high pressure relief valves 44, 40. In the embodiment shown, system pressure is transmitted through a line 8, branch 12 and a restriction 13 to a chamber 25a to act on the upper face of the valve piston 32, through the line 8 to act on the lower face of a spring-loaded piston control valve 20 and through the line 8 and a restriction 10 on the upper face of the latter valve. The chamber 25a is connected to the high- and low-pressure relief valves 40, 44 by a line 39, a further restriction 42 being located between these valves. The throttling effect of the restriction 42 is greater than that of the restriction 10 and that of the restriction 10 greater than that of the restriction 13. On the pressure in the system reaching a value sufficient to open the low-pressure valve 44, flow takes place to reduce pressure both in the chamber 25a and above the valve piston 20. As a consequence the valve piston 20 moves upwardly to connect the line 8 to a line 24 to direct pressure liquid to beneath the valve piston 32 but at this stage the reduction in pressure in the chamber 25a is insufficient to permit upward movement of the valve piston 32. On a further increase in system pressure sufficient to open the high-pressure valve 40 to increase flow, a further reduction of pressure takes place in the chamber 25a to cause upward movement of the valve piston 32 to first close the branch 12 and then interconnect the lines 35, 37 to unload the pump. Owing to a clearance fit between the valve piston 32 and its cylinder 25, which constitutes a filter, liquid from the branch 12 can still pass to the chamber 25a but not in sufficient quantity to prevent closure of the valve 40. Flow through the restriction 42, however, is still sufficient to maintain the valve piston 32 in its raised position and it is not until there is a further fall in the system pressure and closure of the valve 44 that the piston control valve 20 and the valve piston 32 are restored to their lowered positions. In another embodiment, the piston control valve 20 is dispensed with. In this case, the bottom face of the valve piston 32 is in direct communication with the line 8 and parallel branch lines from the line 8 each including a restriction, lead to the chamber 25a. A practical construction of this latter embodiment is illustrated and described in the Specification.

Title: An improved method of controlling exothermic catalytic reactions
IPC: B01J8/22
Filed: 1937-11-26
Abstract: <PICT:0496159/III/1> The temperature of exothermic catalytic reactions is controlled by suspending the catalyst in a fluid capable of absorbing heat and passing this suspension through the reaction zone at a rate sufficient to remove excess heat.  The Figure shows the application of the invention to the synthesis of hydrocarbons from carbon monoxide and steam.  The synthesis gas is fed at 11 into a bubbling tower 10 to which the catalyst suspension is fed through one or more of the pipes 16, 161.  The catalyst may be nickel activated with oxides of aluminium, manganese, or thorium, suspended in an oxygenated organic compound such as partly oxidized paraffin wax.  The suspension leaving the apparatus is recycled through cooler 23 after a part or all of it has been treated for revivification of the catalyst in 26 and fractionated to recover reaction products in 32.  The exit gases are cooled in 37, separated from reaction products in 41, and recycled by line 48.ALSO:<PICT:0496159/IV/1> In the synthesis of hydrocarbons from carbon monoxide and steam, the temperature is controlled by suspending the catalyst in a fluid capable of absorbing heat and passing this suspension through the reaction zone at a rate sufficient to remove excess heat.

Abstract: 537,488. Indicating-apparatus. LANDIS & GYR AKT.-GES. Dec. 22, 1939, No. 32777. Convention date, Aug. 23. [Class 106 (iv)] [Also in Group XXXVI] A thermal indicator for registering the maximum demand on an electricity supply, the maximum indicating pointer of which is moved forward by the pushing member and is secured by means of a panel detent against undesired backward movement, is characterized in that the pawl detent is movable with the maximum indicating pointer and is maintained at all times in engagement with a ratchet wheel that is mounted so as to be capable of turning freely in both directions and is controlled by a brake. As shown, the shaft 2 of the pushing member 1 is rotatable both by a bimetallic spiral 3 subject to the action of the current and by a bimetallic spiral 4 acting in the opposite direction and compensating for variation of room temperature. The maximumindicating pointer 6, which is moved forward over a scale 5 by the pushing member 1 is connected to a lever 7 bearing a spring pawl 9 engaging a ratchet wheel 8, the pointer 6 and lever 7 being fixed on a bush 10 turning freely on the shaft 2. A return spring 11 is connected to the bush 10 and a pin 12 on the plate 13. Between the ratchet wheel 8, loosely mounted on the shaft 2, and the plate 13 is a spring washer 14, which prevents the ratchet wheel 8 from moving on tapping the case of the indicator. The spring 11 prevents accidental forward movement of the pointer 6. The periodic setting back of the pointer 6 is effected by a knob operable from the outside and carrying a driving member acting on the lever 7. The spring washer may be replaced by a cylindrical spring or by a member formed of elastic materials such as india-rubber or leather.

Abstract: 1331166 Molecular pumps ARTHUR PFEIFFER VAKUUMTECHNIK GmbH 14 July 1971 [23 Oct 1970] 32936/71 Heading F1C [Also in Division F2] Bearings for a molecular pump are arranged in housings which are resiliently mounted in the radial direction, at least one housing being mounted movably in the axial direction. The vertical molecular pump shown in Fig. 2 comprises bearings 33, 34 carried by respective housings 35, 36 which are supported by respective pairs of springs 37, 38. Each spring comprises a disc of steel or brass, with a thick coating on both sides of a damping material such as indium, and split as shown in Fig.3 to provide less stiffness in the axial direction than in the radial direction. An upward bias is exerted by a spring 45 so that the upper bearing housing 36 rests against an abutment 39. Oil for lubrication and cooling is supplied to the bearings via flexible conduits 40, 42 made of material of high internal damping. Excess oil from the upper bearing is thrown off by a slinger ring 41 and passes via a duct 43 to a sump 44 which also receives oil dismissing from the lower bearing, the oil being returned from the sump to the oil pump. In another embodiment, Fig. 1 (not shown), having a horizontal shaft, the springs (15, 16) supporting the bearing housings may be plates or diaphragms rather than split discs. The springs may be damped by a coating, of a thickness substantially equal to that of the springs, of indium or lead. Instead, separate damping elements (21) of resilient synthetic material may be provided. Oil is supplied to the bearings through hoses, which may be corrugated, of synthetic material or metal of high damping characteristics.

In a process in which a heavy hydrocarbon oil is contacted at a coking temperature with a body of inert particles having an average particle size in the range of 100 to 1000 microns maintained in the form of a dense turbulent fluidized bed in a reaction zone, a portion of the particles being removed, heated in an extraneous heating zone and returned to the reaction zone to supply heat thereto, a conduit 11 is provided for withdrawing oversized particles, the conduit defining an annular stripping zone 12 in which the circulating particles, free of oversized particles, collect and are stripped with an inert gas. A coking vessel 1 contains a straight-sized section 20, an inverted conical section 30, and a confined stripping section 40. A fluidizing gas, such as steam at a temperature of 400 ‹ F. enters the vessel via pipes 3 and 15. Hot coke from the burner, not shown, enters through line 9, and a reduced crude oil, for example a Hawkins pitch, is fed in through line 2. The product vapours are withdrawn through cyclone 6 and line 4. The conduit 11 has an upper inverted conical section 13, and is perforated at its upper end from point 14. The oversized particles pass out through line 11, and the particles in the desired range pass into the annular zone 12, having baffles 41, and are treated with steam at low velocity entering through lines 15. The particles leave the annular zone 12 through line 16 and pass to the burner. In a modification light hydrocarbons and inert flue gas is used in place of steam. The conditions in the coking zone may be such that the pressure is one to ten atmospheres, temperature 850‹ to 1200‹ F., and the superficial velocity of both the fluidizing gas and the stripping gas 0.2 to 10 ft. per sec.
